# SearxNG Search API
|
|
|
|
This page covers how to use the SearxNG search API within LangChain.
|
|
It is broken into two parts: installation and setup, and then references to the specific SearxNG API wrapper.
|
|
|
|
## Installation and Setup
|
|
|
|
- You can find a list of public SearxNG instances [here](https://searx.space/).
|
|
- It recommended to use a self-hosted instance to avoid abuse on the public instances. Also note that public instances often have a limit on the number of requests.
|
|
- To run a self-hosted instance see [this page](https://searxng.github.io/searxng/admin/installation.html) for more information.
|
|
- To use the tool you need to provide the searx host url by:
|
|
1. passing the named parameter `searx_host` when creating the instance.
|
|
2. exporting the environment variable `SEARXNG_HOST`.
|
|
|
|
## Wrappers
|
|
|
|
### Utility
|
|
|
|
You can use the wrapper to get results from a SearxNG instance.
|
|
|
|
```python
|
|
from langchain.utilities import SearxSearchWrapper
|
|
```
|
|
|
|
### Tool
|
|
|
|
You can also easily load this wrapper as a Tool (to use with an Agent).
|
|
You can do this with:
|
|
|
|
```python
|
|
from langchain.agents import load_tools
|
|
tools = load_tools(["searx-search"], searx_host="https://searx.example.com")
|
|
```
|
|
|
|
